Tea polyphenols is the general name for polyphenols in tea. This ingredient has health functions and is a very commonly used raw material for Chinese patent medicine. Tea polyphenols are extracted from tea leaves using solvent extraction and centrifugal extractor. The extraction rate is high and the extraction effect is good. Research on tea polyphenol extraction is very meaningful.

The tea polyphenols in tea leaves are extracted by solvent extraction. The specific process is as follows:

  1. Crush, alkalize and extract the tea leaves. At this time, tea polyphenols are dissolved in the water.
  2. After pH adjustment, tea polyphenols are released from the water and extracted using solvents.
  3. Tea polyphenols enter the solvent and continue to complete the subsequent purification and crystallization operations.

There are several methods for extracting tea polyphenols. The reason why solvent extraction method is used is that solvent extraction has many advantages, such as: easy to realize industrialization, the entire operation process can be intermittent or continuous production; stable and reliable, high extraction rate, high product purity; and organic solvents can be recycled.

Solvent extraction method and centrifugal extractor have good effects when used simultaneously, with large processing capacity, high extraction rate and good extraction effect, which can meet the production needs of customers. CWL-M centrifugal extractor is a liquid-liquid extraction separation equipment produced by Zhengzhou Tiei Extraction, which can be used for extraction, stripping, washing and other operations in multiple fields.

Advantages of centrifugal extractor for tea polyphenols extraction equipment

  1. Low power consumption, which is only 10% to 30% of traditional extraction equipment.
  2. High extraction efficiency, with product purity of 80% to 98%.
  3. The extraction effect is obvious under the action of centrifugal force, and the processing capacity is large.
  4. It can be operated intermittently, can be operated alone, can be operated continuously in countercurrent, and no interstage pump is required in the middle.

The above is an introduction to the effect of centrifugal extraction of tea polyphenols from tea leaves. For more details about centrifugal extractor, welcome to consult us.
